TOA SPEAKER COMPONENT
LOW-FREQUENCY LOUDSPEAKER
HLS38UL-8/16
DESCRIPTION
The HLS38UL is a 380mm (15 in.) low-frequency
loudspeaker designed for professional applications in
high level sound reinforcement environments such as
studios, theaters, concert halls, auditoriums, discos and
live sound reinforcement applications, where high
efficiency, ultra-low-frequency response, and faithful
reproduction are required. The HLS38UL offers high
power handling capacity and a uniform frequency
response from 30Hz to 3,000Hz. A crossover frequency
high level sound reinforcement environments such as
studios, theaters, concert halls, auditoriums, discos and
live sound reinforcement applications, where high
efficiency, ultra-low-frequency response, and faithful
reproduction are required. The HLS38UL offers high
power handling capacity and a uniform frequency
response from 30Hz to 3,000Hz. A crossover frequency
of 1,000Hz or lower is recommended to obtain smoothest
overall system response. Nominal impedance is 8 ohms
for the HLS38UL-8, and 16 ohms for the HLS38UL-16.
The loudspeaker employs a low-mass 72mm (2.8 in.)
diameter voice coil of edgewound copper ribbon on an
aluminum coil form, which operates in a flux density of
overall system response. Nominal impedance is 8 ohms
for the HLS38UL-8, and 16 ohms for the HLS38UL-16.
The loudspeaker employs a low-mass 72mm (2.8 in.)
diameter voice coil of edgewound copper ribbon on an
aluminum coil form, which operates in a flux density of
14,200 gauss. The voice coil is driven by double ferrite
magnets, which are supported by a rugged diecast
aluminum frame. The cone suspension is made of
exceptionally high- compliance, damped-cloth surround.
